SPECIFICATION forming part of Letters Patent No. 743,381, dated November3, 1903.

Application filed February 13 1903. Serial No. 143,253. (No model.)

To all whom it may concern..-

Be it known that I, WINFIELD O. GUNCKEL, a citizen of the UnitedStates,residingat-Terre Haute, in the county of Vigo and State ofIndiana, have invented certain new and useful Improvements inGable-Grips; andIdo hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to automatic grips used on mine-cars oncable-railroads; and it consists in the novel construction andcombination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of a cable-grip constructedaccording to this invention. Fig. 2 is an end viewof the same. Fig. 3 isa side view of a modified grip. Fig. 4 is a plan view from below of thegrip shown in Fig. 3. Fig. 5 is a side view of another modification ofthe grip. Fig. 6 is an end view of the grip shown in Fig. 5.

A is a portion of the bottom of a mine-car which runs on rails in theordinary manner 7 B is the cable, provided with grip membersor balls (2,by means of which the cars are drawn along the rails, said'parts beingalso of any approved construction and material.

In the form of the invention shown in Figs. 1 and 2 a single bracket Cis secured to the bottom of the car and is provided with a pivotpin 0. Drepresents arms, which are pivoted on the pin 0. These arms project inopposite directions and are inclined downward. These arms have heels orstops d, which bear against the bracket and prevent the arms fromdescending, but which permit the free ends of the arms to rise. The freeends of the arms D are provided with curved and forked claws E, theforked portions 6 of which engage with the balls on the cable. The clawsE (shown in Figs. 1 and 2) are pivoted to the free ends of the arms D bypins f and are provided with stops g, which permit the claws to moveinward or toward each other on their pivots, but which prevent them frommovingoutward. H represents guide-loops secured to the bottom of the carand engaging with the free end portions of the arms D. These guideloopsmay be dispensed with in this form of.

the device, if desired, or they can be used to prevent the arms frombeing displaced laterally, if necessary.

In the modified form of the grip shown in Figs. 3 and 4: two brackets Oare used instead of the single bracket 0 and the arms D are pivoted onpins 0 in these two brackets, so that they project in oppositedirections, the same as hereinbefore described. The guideloops H arealso used as supports for the arms to prevent them from descending lowerthan desirable. In this form of the device the curved and forked claws Eare formed integral with the arms instead of being pivoted to them; butotherwise the claws are the same as hereinbefore described, and theclaws might be pivoted to the arms, as hereinbefore described, if founddesirable.

In the modified form of the-grip shown in Figs. 5 and 6 the claws E arealso formed integral with the arms D; but the arms are pivoted to asingle bracket 0, the same as in Fig. 1, instead of being pivoted to twobrackets, as shown in Fig. 3.

In operation all these grips are similar to each other. The ball on thecable lifts the forked claw at one end of the grip and passes intoengagement with the claw at its other end. The car is drawn along by thecable on level ground and on upgrades. When the car descends a steepdowngrade and begins to run faster than the cable, the rearmost claw ofthe grip engages with the ball on the cable, so that the car does notcontinue to run faster than the cable and does not acquire adangerousrate of speed.

What I claim is- 1. In a cable-grip, the combination, with a support, oftwo downwardly-inclined arms having their upper ends pivotally connectedwith the said support and projecting in opposite directions, means forpreventing the arms from moving downward but permitting them to moveupward, and grip-claws carried by the free ends of thesaid arms,substantially as set forth.

2. In a cable-grip, the combination, with two supporting-brackets, oftwo downwardlyinclined arms having their upper ends pivoted to the saidbrackets and projecting in opposite directions, means for preventing thearms from moving downward but permitting them to move upward, and curvedand forked I limiting the outward movements of the said 10 grip-clawscarried by the free ends of the said claws, and means for limiting thedownward arms, substantially as set forth. movements of the said arms.

3. In a cable-grip, the combination, with a In testimony whereof I affixmy signature 5' support, of two arms having their upper end in presenceof two Witnesses.
